Abstract: Against the backdrop of China's heavy truck industry with an annual output exceeding 1.2 million units, the coil material handling and tape cutting processes in frame longitudinal beam rolling production lines have long been plagued by inefficiency, high safety risks, and heavy reliance on manual labor. These manual operations account for 35% of production accidents, severely compromising safety and productivity. This paper aims to achieve fully automated coil feeding through integrated automation and digital technologies, reducing operational costs while enhancing safety. The solution employs truss manipulators to replace manual lifting with double-girder cranes, and robotic untying to replace manual operations. By integrating control systems with warehousing systems, it enables real-time data exchange between coil storage, lifting routes, and production requirements. This innovation boosts feeding efficiency, minimizes human involvement, reduces safety risks, and advances the manufacturing of heavy truck frame longitudinal beams toward digital unmanned workshop goals.
